You should get rid of krokodile, use hippowdon instead of it to handle conkeldurr and put rocks, so you can use power whip on ferrothorn instead of dual hazzards, knock is still an option to punish greedy conkel players and making magnezone job easier.
Also change thunderbolt for ice beam on starmie to hit dragontypes such as hydreigon which is threatening for your team, and having zone and ferro for water types is enough.
